How do you experience OCPD?

Is it OCPD if you have a bunch of "hobbies" that you spend the majority of your hours on?
Often one hobby will be dominant for a period of months to years, and then suddenly replaced by a different hobby? When you're not engaged in the activity, you're thinking about it, or about buying new equipment related to that hobby, or reading books about how to do it better?
To the point where if you have an unstructured schedule (such a grad student might have), you spend virtually no time working on your dissertation? Or, perhaps one specific subproject of my dissertation itself might become the "hobby" du jour and then I will work on that for 22 hours / day on that (making my advisor rather happy) until that particular project is done, and then go back to not caring about my thesis anymore.
Or that you have a mental jukebox that is on during every waking hour. There's always a song in my head. It is often something I've heard recently although sometimes something random comes on and I can barely remember how many years it's been.
Or that you get obsessed with a fantasy about a woman, often from a single brief pleasant interaction? When you actually get into a real relationship, sometimes that relationship starts to feel all-consuming of your mental energy?
Does all of this sound like OCPD?

Because I was recently diagnosed with PD-NOS. OCPD was one of the strongest components in my personality test, along with narcissism and antisocial. So I've been reviewing the pattern of obsessions I've had going back about as far as I can remember as a conscious human being so figure out how this fits in.

Scoring: Most people fall in the middle band between about 50 and 75, but anywhere above 70 means you’re having a problem.
It’s important to get other people who know you well to share in this rating – it can be illuminating and even fun.

25-45 = not uptight;
46-55 = usefully OC;
56-70 = moderately OC;
>70 = danger zone!

Interpreting Your Responses
If you find yourself answering "yes" to more than just a few of these questions, you (or your loved one) are probably at least somewhat obsessive. Now look once again at the questions to which you answered "yes," and for each one, answer a second
question: Does this characteristic cause difficulties in relationships, work, or leisure activities, or does it interfere with your ability to enjoy life in general? If you answer "yes" to this even once, you will benefit from learning more about obsessiveness and about the possibility for change. If you are strongly obsessive, you're a careful person who finds security in sameness and predictability. You're more wary of change and newness than the average person – and changing isn't easy for anyone! But change is always possible. It may involve time and struggle. It may occasionally be painful. But it can be a journey toward a happier, more relaxed and fulfilling life.

Mr. Sfguy-

I was not diagnosed with this disorder, but I feel that I relate very strongly to some of the traits.

It is very difficult to explain my “compulsions” now as an adult. Childhood however is much easier. Looking back, one thing that stands out was how I played video games. When I purchased a new video game I would spend hours/days/weeks in the backend/settings of the game. Sound had to be perfect, character, sliders, options, etc… Test and re-test to make sure everything was perfect. When this was finally completed, and I felt satisfied, I would start the game. I would play the game for maybe an hour or two, turn it off, and go trade it in for another game. Start the cycle again.

I never beat a single game.

Thank you,

Harris
